1) be very very very carefull when you use '--force' for 'git push', you can broke whole repository, you should notify other developers on alsa-devel mailing list that you will do this change for 'master' branch

2) valid 'Signed-off-by:' line must be in the commit text

[edit]Rules for alsa-kernel.git and the mirror branch in alsa-driver.git

Note: Especially after 'git rebase' the repository on server is not consistent with local repository (remote ref is not ancestor of the local ref for master branch), so you have to use --force parameter for 'git push' command. Note that this might be dangerous - please, ask Jaroslav Kysela < perex at perex . cz > if you can do this for branch 'master'.
